Detailed Description

This file contains C-wrappers to the BLAS (Basic Linear Algebra Subprograms) routines that are used by BCLS. Whenever possible, they should be replaced by corresponding BLAS routines that have been optimized to the machine being used.

Included BLAS routines:

• cblas_daxpy
• cblas_dcopy
• cblas_ddot
• cblas_dnrm2
• cblas_dscal
